ECC83 tube based guitar preamplifier. First test.
Once again an interesting circuit. Okay, to combine it with a tube preamp and a fuzz face! What happens if a small powerful tube amplifier, and combined with the classic fuzz effect? What kind of sound will be the result?
It is a low voltage tube preamplifier, specifically guitar preamp. Uses 12AX7 or ECC83 tube. No complicated circuit. The circuit is similar to the famous old guitar amplifiers bright channel. Low voltage operation, does not require a separate anode and output transformer.
Matsumin wrote in his drawings ValveCaster 2007, the goal was to create a real tube boost / overdrive pedal that can run on a single 9-volt battery. It worked! Unfortunately defecate 9V battery snap. Valvecaster run well in a 9 or 12-volt power supply. 12V will give you more headroom and cleaner sound. It is designed with single coil pickups. A 12AU7 is particularly suited to this, by virtue of being virtually identical to a 12U7 which was designed to be used at low voltages in old car radio circuits. Indeed some sources say that there isn’t really a difference…
Real tube guitar distortion effects. unusual solution works of 2n7000 mosfet transistor. After the transistor is like the valve amplifier, it is very nice and pleasant natural sound of this effect provides a true analog distortion, no digital, no modeling!
A lot of effects pedals has been prepared, including the famous Tube Screamer to mimic the old natural distortion of a tube amplifier. These pedals operate a semiconductor basis, more – less successfully mimic this sound. I did this and I use it with great joy:
New real tube distortion guitar effects. Mini tube amp, very full sound, beautiful tone. With 12AX7 tube distortion pedal made.
In this article we take a closer look at a bit of a tube guitar amp ECC83 topic. Considering dual triode structure, which means that two of the same reinforcing element is a glass envelope closed. As will become apparent in the US or the Russian 12AX7 tube 6N2P (6Н2П) signal, which is not quite the same, but rather similar; here it is already different from the heater connection. Why is it so popular?
